Abstract

To allow the driver of a vehicle to see oncoming traffic in the opposite lane, the rearview mirror (1) of the vehicle houses a television camera (2) connected to a video amplifier and the latter to a television screen inside the vehicle.
The camera (2) is mounted on a telescopic rod (3), and under control of a lever actuated switch a motor produces the opening of a window (7) in the rearview mirror, and the extension of the telescopic rod (3), moving the camera to a position away from the vehicle.

Description

    OBJECT OF THE INVENTION
  • The present invention, as is expressed in the title of this specification, consists of an improved rear-view mirror whose purpose is to allow one to see the lane opposite the driver, who is going to pass. Therefore, the invention makes it possible to see the presence of a vehicle coming head on, when one is going to pass, thus avoiding passing from starting when danger exists.
    • BACKGROUND OF THE INVENTION
  • Conventionally, rear-view mirrors are known which are located outside of the vehicle, on the driver's side as well as on the passenger's side, by which the possible vehicles that can approach by the rear, on the left as well as on the right, are seen in such a way that the driver can detect the presence of a vehicle that approaches in the rear upon changing lanes in order to pass.
  • On the contrary, when the driver faces the need to pass he does not have any device which permits him to see the opposite lane, in order to detect the presence of a vehicle in the opposite direction, for which purpose it is necessary to stick out the "nose" of the vehicle to determine whether or not another vehicle is approaching in the opposite direction, with the subsequent risk entailed in such an operation.
    • DESCRIPTION OF THE INVENTION
  • In order to solve the above cited inconveniences, the invention consists of an improved rear-view mirror which permits one to see the opposite lane, each time that it is necessary to pass.
  • For this purpose the invention has a rear-view mirror inside of which a small television camera placed on the end of a telescopic rod, inside which runs a coaxial cable through which the images captured by the camera are sent, is coupled.
  • Besides, the telescopic rod has inside it a strip which is related to a toothed wheel which is moved, by some toothed pulleys, by a motor, so that upon activating the operation of said motor, the extension of the telescopic rod towards the outside of the mirror takes place, so that the latter has on its side a window that opens at the same time that the motor is operated, in such a way that the camera moves toward the outside a certain length, equivalent to the extension of the telescopic rod.
  • The inside of the vehicle has an image amplifier that is connected by means of the coaxial cable that runs through the telescopic rod to the television camera, in such a way that the images detected by the same are picked up.
  • On the other hand, the image amplifier is connected to a cathode ray tube or screen through which the image detected by the television camera placed on the end of the telescopic rod is materialized.
  • Obviously, the television screen remains located in the dashboard in an adequate place.
  • In this way, each time that a driver is in the position requiring the passing of another vehicle, the driver by means of a lever that controls a switch, activates the motor, causing the window to open and the television camera to go outside, at the same time that the television screen is turned on, in such a way that the driver of the vehicle can see the possible vehicles that are coming head on in the opposite direction, without the need to stick out the "nose" of the vehicle, thus reducing the risks always entailed in passing.
  • Once the operation has finished, the lever that controls the switch is moved so that in the first place the telescopic rod retracts, until the television camera, placed on the end thereof, remains hidden inside the mirror, which is when the window placed in one side of the rear-view mirror closes, at the same time that the television screen is turned off, remaining in an inoperative state until it is necessary to use the same in order to pass another vehicle.
  • Hereinafter, to make it easier to understand this specification and forming an integral part of the same, a series of figures is attached in which the object of the invention is represented in an illustrative non-restrictive manner.
    • BRIEF DESCRIPTION OF THE FIGURES
  • Figure 1.- It shows a general diagram of the elements that make up the improvements of the rear-view mirror, in accordance with the invention.
  • Figure 2.- It shows a partially sectioned view of the improved rear-view mirror of the invention, from which the telescopic rod emerges through the window placed in said mirror, the telescopic rod having on its end the television camera which makes it possible to see the cars that come head on in the opposite direction.
  • Figure 3.- It shows a view of the mechanical part of the invention, by means of which the extension and retraction of the telescopic rod is made possible, as well as the opening of the window placed in the rear-view mirror.
    • DESCRIPTION OF AN EMBODIMENT
  • Hereinafter a description of the invention is made based on the above cited figures.
  • Thus, the invention consists of an improved rear-view mirror whose purpose is to permit one to detect the presence of a vehicle that is coming head on and in the opposite direction of the vehicle that includes the improved rear-view mirror of the invention, thus reducing the risks entailed always in passing.
  • In order to obtain the above cited aims, the rear-view mirror (1) has a television camera (2) that remains placed on the end of a telescopic rod (3), inside which runs the coaxial cable (4) through which the signals corresponding to the image captured by the television camera (2) are sent.
  • The television camera (2) is connected, by means of the coaxial cable (4) to an image amplifier (5), which in turn is connected to a cathode ray tube or television screen (6), so that through it the images captured by the television camera (2) are seen.
  • The telescopic rod (3) folded up is included inside the rear-view mirror (1.)
  • The telescopic rod (3) includes inside it a strip (11) which is related to a toothed wheel (12), which is moved by means of a worm (13) in the end of which there is a toothed pulley (14) that is related by means of a toothed belt (16) with another toothed pulley (15) included in the shaft of a motor (10.) This entire unit is included inside the rear-view mirror.
  • The rear-view mirror has a window (7) through which the extension of the telescopic rod (3) is permitted upon activating the motor (10), just as is explained hereinafter.
  • Thus, upon activating the motor (10) by means of a lever (8) located on the steering wheel (9), the rotation of the toothed belt (15) is produced which at the same time produces the rotation of the toothed pulley (14) by means of the toothed belt (16), whereby the worm (13) produces the rotation of the toothed wheel (12) which operates the strip (11) included inside the telescopic rod (3.)
  • At the same time that the activation of the motor is produced, either by the same or by another device, the window (7) included in the rear-view mirror (1) is opened, thus permitting the extension of the telescopic rod (3) towards the outside, and therefore the television camera remains located outside the vehicle.
  • Besides, upon moving the lever (8), the image amplifier (5) and the television screen (6) are turned on, in such a way that this permits the images captured by the television camera (2) to be seen on the screen.
  • Therefore, each time that the driver needs to pass, he moves the lever (8) producing the above cited turning on sequence, in such a way that the television camera (2) remains at a distance from the vehicle, capturing the images located in front of the vehicle in the opposite lane, which facilitates seeing cars that are coming head on, without the need to stick out the "nose" of the vehicle to see whether any other vehicle is coming in the opposite direction head on, facilitating the passing operation and reducing the risks that such an operation always entails.
  • Once the passing has concluded or when the service of the television camera is no longer needed, the lever (8) is moved again in such a way that the image amplifier (5) and televesion screen (6) are turned off, at the same time that the motor (10) is activated in the opposite direction producing the retraction of the telescopic rod (3) and therefore of the television camera (2), remaining included in the rear-view mirror (1) and the window (7) included in said rear-view mirror (1) closing.

Claims (2)
